Cable of a butterfly valve

In salon the cable of a butterfly valve (1) with the nipple (3) under which the spring is enclosed, is suspended in a bifurcate eye on the top end of a pedal of gas (2) as is shown here.


Valves of injection (5, 6, 7 and 8) are removed together with a distributive tube (3) and the regulator of pressure (4). For this purpose disconnect pipelines of giving (2) and return (1) fuel and unscrew bolts of a distributive tube.


Management of a butterfly valve in the engine with a working volume of 1,6 l

The arrow indicates the nipple recorded by a fixing bracket on the end of a cable of a butterfly valve.

1 – cover of a cable of a butterfly valve;
2 – demountable clamp;

3 – countersupport;
4 – lever of a butterfly valve.

Arrangement of elements of management of a butterfly valve in a motive compartment (the engine of 1,8 l)

The arrow showed the nipple recorded by a fixing bracket on the end of a cable of a butterfly valve.

1 – cover of a cable of a butterfly valve;
2 – demountable clamp;
3 – countersupport;

4 – cable of a butterfly valve;
5 – lever of a butterfly valve.

The connecting cable between a pedal of gas and a branch pipe of a butterfly valve should not be bent. During works in a motive compartment it is necessary to track that the disconnected cable was not difficult under an adverse corner owing to what it could be damaged.

Replacement of a cable of a butterfly valve

 PERFORMANCE ORDER

  1. In a motive compartment remove on the end of a cable a fixing bracket and in a point of fastening of a cover of a cable a demountable clamp.
  2. In salon dismantle facing under a control panel, see the head Salon at the left.
  3. Take out a fixing nipple of a cable of a butterfly valve from an eye in the top part of a pedal of gas.
  4. Squeeze out a rubber tip from a back wall of a motive compartment.
  5. Turn a tip in a partition to salon on 90 ° to the left and take out it.
  6. Extend a cable of a butterfly valve.
  7. Do not bend a new cable of a butterfly valve at an insert of rubber tips in a partition.

Adjustment of a cable of a butterfly valve

 PERFORMANCE ORDER

  1. Wring out up to the end a gas pedal.
  2. Put the lever of a butterfly valve in the provision of full supply of gas.
  3. Insert a demountable clamp in corresponding to risk of a cover of a cable of a butterfly valve on a countersupport.
  4. At the lever of a butterfly valve at completely wrung out gas pedal the gap has to be at most 1 mm.

 Council: After a detachment of sockets of the control unit of system of ignition/injection of Motronic, and also after shutdown of the accumulator in the control unit all sizes received as a result of so-called training are erased. Independent adaptation of the control unit to data of the engine "is forgotten", and there can be too high or unstable turns of idling. During a short trial trip the control unit "is trained" in adaptation to data of the engine. Though process of training is blocked if in the computer information on constant malfunction is brought. In this case in the beginning it is necessary to consider a memory with malfunctions and to erase information. The sporadic defects arising, for example, at the expense of a detachment of the socket of any sensor do not interfere with training process.
